Patent number: 8042636Abstract: A water-cooled engine mounted on a vehicle wherein a mass concentration keeps the center of mass at a low position. In a saddle-ride type four-wheel vehicle, a radiator and a fuel tank are supported on lower frames, and are arranged, side by side, so as to be distributed respectively on the right-hand side and on the left-hand side so as to overlap each other when viewed from a side. In addition, the fuel tank and the radiator are disposed at the rear of a front suspension arm and at the rear of an engine. As a result, the concentration of mass and the keeping of the mass at a lower position are achieved. Moreover, the fuel tank and the radiator are allowed to stretch outwards beyond the upper frames. Consequently, the fuel tank can have a larger capacity and a ventilation path that leads to the radiator can be secured.Type: GrantFiled: March 26, 2008Date of Patent: October 25, 2011Assignee: Honda Motor Co., Ltd.Inventors: Seiji Hanafusa, Akihiro Yamashita, Takuya Yamada

Patent number: 7864658Abstract: A multicarrier communication method selects carriers on the basis of an SN-ratio and the balancing of a transmission line. Available carriers are selected in accordance with the balancing of the balanced transmission line, in which the balancing is measured at either a sending terminal or a receiving terminal or alternatively at both, and the SN-ratio is measured between the sending terminal and the receiving terminal. Additionally, a modulation method having the greatest permissible multivalue is selected for each of the carriers, wherein the carriers are selected in light of the SN-ratio and balancing, or alternatively in a highest-to-lowest order of frequency. Transmission power is controlled for each of the carriers to suppress radiated emission, and the SN-ratio and balancing are measured at predetermined time intervals to renew the selection of the carriers and the selection of the modulation methods.Type: GrantFiled: September 14, 2004Date of Patent: January 4, 2011Assignee: Panasonic CorporationInventors: Toshiyuki Wakisaka, Masahiro Maki, Hisao Koga, Yuji Igata, Fumio Ichihara, Akihiro Yamashita, Tsunehiro Hanada, Mutsuhiko Oishi
